Lightheadedness: Causes, symptoms, Treatment, Prevention

We have all been through it at some point or another in our lives. The world suddenly starts spinning, we feel woozy and faint and may want to puke, our vision may blur and our heart starts pounding in our chest. It’s probably lightheadedness.

What is lightheadedness?

Lightheadedness is a sensation when one feels faint or is about to lose consciousness. Nearly 40% of adults in the US experience it at least once in their lifetime. While it may seem daily innocuous it can be the marker for a more serious underlying condition. Collapsing due to lightheadedness can also result in serious injuries. Let’s find out more about this condition.

Causes of Lightheadedness

When we are trying to figure out the causes of lightheadedness, the etiology can be quite varied. Here are a few causes and conditions that can cause lightheadedness. 

  1. Dehydration: A lack of water in the body is a frequent cause of lightheadedness and is often seen in the summer months or after strenuous activity. A dehydrated state can cause a drop in blood pressure and lead to giddiness.
  2. Low blood sugar: Low blood sugar can cause lightheadedness. The condition is known as hypoglycemic syncope. According to stats, hypoglycemic syncope is the most common metabolic syncope, with a reported incidence of 0.6% in diabetic patients and 4% in diabetic patients who take insulin. Hypoglycemia is common in diabetics who may have skipped a meal or undergone any strenuous activity. 
  3. Anaemia: A lack of red blood cells can cause wooziness, as the body is not getting enough oxygen. Anaemia is more commonly seen in women and is most commonly caused due to iron deficiency. 
  4. Low blood pressure: When blood pressure drops too low, blood supply to the brain may be diminished. A sudden change in position can cause a reeling sensation known as postural hypotension.
  5. Medications: Certain medications, such as those used to treat high blood pressure, anxiety, or depression, can cause lightheadedness as a side effect. Researches show that ACE inhibitors, used to treat hypertension can lead to hypotension in certain cases.
  6. Inner ear disorders: Our ears not only help us in auditory functions but also maintain body balance. Disorders of the inner ear, such as Meniere’s disease, can cause lightheadedness and vertigo. 
  • Syncope: Syncope is a loss of consciousness due to a transient lack of blood supply to the brain. One of the pre-symptoms of syncope is dizziness.  
  1. Heart problems: Cardiac and circulatory problems, such as a heart attack or arrhythmia, can present wooziness as a symptom. It may also be due to a stroke
  2. Hyperventilation: Breathing too quickly or deeply can cause dizziness. This can be a result of stressful states. The unsupervised or untrained practice of breathwork such as the Wim Hoff method or pranayam can cause lightheadedness.

Symptoms of Lightheadedness

The most commonly seen symptoms of lightheadedness are the feeling that the surroundings are spinning and that you are going to pass out.

Other symptoms include

Diagnosis of Lightheadedness

While some causes are harmless, others can be fatal hence a careful investigation is imperative for a proper diagnosis. A detailed history, examination and symptoms are sufficient for a medical professional to diagnose lightheadedness. Your healthcare provider may prescribe further tests to ascertain the underlying pathology. These tests can include

  • Blood Tests: Blood work can help identify if the lightheadedness is caused by anemia, hypoglycemia, or other metabolic imbalances.
  • ECG (Electrocardiogram): An ECG tells the doctor about your cardiac function and helps to diagnose heart problems that may be causing lightheadedness.
  • Tilt table test: This test involves lying on a table that tilts to simulate changes in position. It can help diagnose conditions such as orthostatic hypotension, which is a drop in blood pressure upon standing up.
  • Vestibular function tests: These tests evaluate the function of the inner ear, which can help diagnose conditions such as Meniere’s disease.

Imaging tests: Radiographs or other Imaging tests such as CT or MRI scans may be ordered if a healthcare provider suspects that the lightheadedness is caused by a problem in the brain or inner ear.

The treatment of lightheadedness involves understanding the underlying cause and treating it. Here are a few at-home remedies that you can try for curing lightheadedness.
